Specification of {.etters Patent.

Patented Apr. 26, 1921.

Application filed May 11, 1920. Serial No. 380,704.

T 0 all whom it may concern:

Be it known that I, JOHN SHINE, citizen of the United States, residing at Houston, in thezcounty of Harris and State of Texas, have invented certain new and useful Improvements in Attachments for Internal- Combustion Motors, of which the following is a specification.

This invention relates to new and useful improvements in an attachment for internal combustion motors.

One object of the invention is to provide a device of the character described which has been specially designed forthe purpose of admitting auxiliary air into the intake manifold of an internal combustion motor.

Another object is to provide an attachment ofthis character whereby either hot or cold air may be admitted as desired.

A further feature resides in the provision of means whereby the intake of auxiliary air may be controlled or entirely cut off.

WVith the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a side view of a motor with the attachment applied thereto, and

Fig. 2 shows a plan view of the air intake pipe- Referring now more particularly to the drawings wherein like numerals of reference designate similar 'parts in each of the figures, the numeral 1 designates the motor, the numeral 2 refers to the intake pipe and the numeral 3 refers to the intake manifold. The carbureter (not shown) is usually attached to the lower end of the pipe 2 and between it and the manifold there is tapped into said pipe an air inlet tube 4. .The other end of this tube is secured to the bracket 5 which is fastened to the side of the motor. The tube at has the controlling valve 6 which is operated from the vehicle dash board 7 through the valve rod 8. An auxiliary air pipe J lies alongside the motor and. has one end, 10, downwardly turned and fitted into the bracket 5 and secured therein by the set bolt 11. Ordinarily the free end of the pipe 9 is turned rearwardly and the air passing through it comes from around the motor and is consequently hot and therefore.

conduces to a more perfect vaporization of the fuel, a better mixture and consequently a more perfect combustion. If the engine gets too hot and a cooler auxiliary air is required the set bolt 11 may be loosened and the pipe 9 turned around, as shown in dotted lines in Fig. 1', and it will then receive cool air from the fan 12.

that I claim is:

A motor attachment including an inlet conduit, one end of which enters the intake pipe of the motor and the other end of which lies upon the exhaust pipe of the motor and is movable so as to take cold air directly from the motor fan and a means operable from the dash of a vehicle for controlling said air inlet.

In testimony whereof I have signed my name to this specification.

JOHN SHINE.
